A TTORNEY United States Patent O SUPPORTS Hanoh Charat, Dallas, Tex.

Application October 6, 1952, Serial No. 313,235

2 Claims. (Cl. 248-317) This invention relates to supports, and more particularly to a support for supporting a device within the radiator of internal combustion engines.

Automobiles, trucks and other vehicles having internal combustion engines are now usually provided with radiators in which the cooling liquid is maintained under a constant superatmospheric pressure by a pressure cap which closes the filler spout of the radiator. The pressure cap is provided with a Sylphon cell, a spring, or other pressure responsive means, which opens the filler spout when the pressure within the radiator exceeds a predetermined value to relieve the pressure. The radiators are subject to corrosion and scaling due to the pressure of impurities in the cooling liquid. Catalytic water treating or corrosion inhibiting cells of the type disclosed in the co-pending application, Serial No. 172,869, now abandoned, filed July 10, 1950, by Andre Barbier, have proven very effective in inhibiting corrosion and reducing the deposition of scale and sludge in radiators. Such catalytic corrosion inhibitors include a catalytic cell which must be immersed in the cooling liquid, and it is necessary to provide a support for suspending or supporting such a catalytic cell in the radiator. The support should preferably be of such structure that it may be easily installed and removed from radiators and that it may be employed in pressurized radiators with pressure caps without affecting proper functioning of the latter.

Accordingly, it is one object of the invention to provide a new and improved support for supporting a device within the radiator of an internal combustion engine.

It is another object of the invention to provide a new and improved support for supporting a catalytic cell in a pressurized radiator having a pressure cap for. closing the filler spout thereof, which support does not affect the sealing of the filler spout by the pressure cap.

Further objects and advantages of the invention will readily be apparent from the reading of the following description of devices constructed in accordance with the invention, and reference to the accompanying drawings thereof, wherein:

Figure 1 is a fragmentary vertical sectional view of a radiator showing a preferred embodiment of the support in position in the filler spout of the radiator and supporting a catalytic cell within the radiator,

Figure 2 is a top plan view of the support shown in Figure 1,

Figure 3 is a sectional view taken on line 3--3 of Figure 2,

Figure 4 is a top plan view of a modified form of the support, and

Figure 5 is a sectional view taken on the line 55 of Figure 4.

Referring now to the drawing, the reference numeral 14) designates a pressurized radiator having the usual filler spout 11. The filler spout is provided with an outturned flange 12 which is engaged by the inturned flange 13 of a pressure cap 14 in the usual manner to retain the pressure cap in the filler spout. The filler spout is also provided 2,744,715 Patented May 8, 1956 with an internal annular ledge 15 which the pressure cap sealing disk 16 normally abuts to close and seal the filler spout so that a predetermined pressure may be maintained in the radiator. The disk 16 is biased downwardly toward the annular ledge 15 by the pressure cap spring 17 and is guided and limited in its downward movement by a headed post 18 extending downwardly from the bottom of the pressure cap.

The support for holding a catalytic cell 19 in the radiator immersed in the water or cooling liquid of the radiator includes a substantially flat annulus or ring 20 which is insertable in the filler spout 11 to rest on the annular ledge 15. The ring 20 is continuous or solid so that a gas and liquid-tight seal is formed between the annular ledge and the underside of the ring and also between the disk 16 and the upper side of the ring when the pressure cap is in position closing the filler spout. When the pressure within the radiator exceeds the predetermined value, the disk 16 is moved upwardly against the resistance of the spring to break the seal between the disk, ring and annular ledge so that the pressure within the radiator is relieved by escape of gas or steam from the radiator.

A finger piece 21 has one end integral with the ring 20 and the other free end bent downwardly. A chain 22 or other connecting element has one end attached to the free end of the finger piece and the other to the catalytic cell 19 to hold the cell in proper position in the radiator. The chain 22, being attached to the lower end of the finger piece, is prevented from contacting and wearing on the sides of the filler spout and the radiator, and also prevents any contact between the chain and the pressure cap which could impair the function of the pressure cap.

It will be seen that the support for holding a catalytic cell 19 in a radiator includes a flat ring 20 which may be easily installed in the filler spout of a radiator to rest upon the annular ledge 15 thereof and seal between the ledge and the sealing disk 16 of a pressure cap 14 so that the function of the pressure cap is not impaired in any way by the use of the support. Moreover, it will be seen that a downwardly inclined finger piece 21 integral with the ring has a lower free end to which may be connected by any suitable means, such as the chain 22, a catalytic cell 19, so that the catalytic cell is supported in proper position within the radiator, and water or other fluids may be added to the radiator in the usual manner without interference by the support. Furthermore, it will be evident that the ring 20 and the cell 19 can be easily removed from the radiator whenever this becomes desirable.

In Figures 4 and 5 is illustrated a modified form of the support shown in Figures 1 to 3. The flat ring 30 is a solid annulus which may be positioned on the ledge 15 of a radiator in the same manner as the ring 20 described above and which functions in the same manner as the ring 20 to seal between the disk 16 and the ledge 15.

Instead of the finger piece 21, however, the ring 30 is provided with a cross member 31 which is expanded and crimped downwardly to a V-shape. A chain 32 or other connecting element has one end connected to the lowermost position 33 of the cross member and its other end to the catalytic cell 18. This connection of the chain 32 at a point spaced below the annular ledge 15 prevents any contact between the pressure cap and the chain and also between the chain and the sides of the filler spout.

While a flexible chain has been shown as the connecting element between the finger piece 21, the cross member 31 and the catalytic cell, it will be obvious that a flexible wire, cable or even a rigid member could be used as connecting elements instead of such chains.

The foregoing description of the invention is explanatory only, and changes in the details of the construction illustrated may be made by those skilled in the art, within the scope of the appended claims, without departing from he spirit of the invention.

What I claim and desire to secure by Letters Patent is:

1. A support for holding an article in a radiator having a filler spout provided with an inwardly extending ledge, and a pressure cap adapted to abut said ledge to close and seal said filler spout, including: a continuous thin flat annulus adapted to rest on said ledge and be engaged by said pressure cap and to be contacted by both said ledge and said pressure cap to provide a seal therebetw'een; a supporting member integral with and formed of the same material as the annulus, and of the same thickness as the annulus, said supporting member extending inwardly from and beyond the inner periphery of the annulus and bendable downwardly below the plane of said annulus, so as to be free of engagement by the pressure cap or the ledge; and a flexible chain connected at one end to the inner end of the inwardly projecting member and hanging free therefrom for freely swingably securing an article to said inner end of said supporting member.

2. A support for holding an article in a radiator having a filler spout provided with an inwardly extending ledge, and a pressure cap adapted to abut said ledge to close and seal said filler spout, including: a continuous thin flat annulus adapted to rest on said ledge and be engaged by said pressure cap and to be contacted by both said ledge and said pressure capv to provide a seal therebetween; a supporting member integral with and formed of the same material as the annulus and extending across said annulus and having opposite ends integral with the inner peripheral edge of the annulus and having a lower intermediate portion extending below the plane of said annulus; and swingable connecting means secured to the lower intermediate portion of said supporting member and swingable freely therefrom for securing an article to said supporting member.
